Novel radioactive and non-radioactive iodobutyrophenone derivative and processes for the preparation thereof.

摘要

A radioactive or non-radioactive 2-iodobutyrophenone derivative has the formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="29" wi="87" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein X is a radioactive or non-radioactive iodine atom. The radioactive compound has a high affinity for dopamine receptors and is very useful as a radioactive diagnostic agent and as a radiopharmaceutical, and the nonradioactive compound also has a high affinity for dopamine receptors and is very useful as a neuroleptic, a sedative, an anodyne, a tranquilizer, etc.
